Rename IAuthorizationHeaderProvider2 to BoundAuthorizationHeaderProvider (#235)

Renamed `IAuthorizationHeaderProvider2` to `BoundAuthorizationHeaderProvider` and updated its functionality to create authorization headers with an optional certificate binding for mTLS Pop. This change is unlikely to affect users as the interface was introduced in the previous version.

+## Breaking changes
+Rename `IAuthorizationHeaderProvider2` to `BoundAuthorizationHeaderProvider`. This interface extends `IAuthorizationHeaderProvider` to  create authorization headers with a token which is optionally bound to a certificate (for mTLS Pop). For details, see [PR #232](https://github.com/AzureAD/microsoft-identity-abstractions-for-dotnet/pull/232)
+
+In practice, it's unlikely that this breaking change affects anybody as the renamed interface was new in 9.6.0, and not yet used to the team's knowledge.
